N erica l ssen-HOLDER. Y

T0 aZ/Z whomt may concern: v

.Be it known that I, MAX RAGHLIN, a citizen of Russia, and a resident of the city of New York, in the county of Kings and State of New York, have invented certain newand useful improvements in Sash-Holders, of which the following is a specification. n

Thepresent invention krelates to improvements in sash-holders, and more particularly to that class which includes springpressed rollers in engagement with an ele.- ment of the window, so as to hold the sash in any desired position. v

1n devicesl of this type, the rollers are usually held by springs in frictional engagcment with the windowr element, the springs being so dimensioned that the pressure exerted thereby is in excess ,ofv the weight of the sash. ln practice ithas-been found, however, that, in time, the springs ylose to some extenttheir tension, the result being that the sash descends if` lightly touched, and sometimes even under wind pressure.

The main object of the present invention is to provide a roller carrying sash-holder, which -in its operation does not depend solely upon the friction produced,y by springs, but includes interlocking elements on .the roller and window.;y W

Another object of the invention-is-to produce a device of Ythe character mentioned which is simple in construction, durable and efficient in operation.

A further object of the invention is to provide a sash-holder which acts at the same time as a means for' preventing rattling of the window sashes.

A still further object of the invention is to provide a sash-holder which is capable of manufacture on a commercial scale, or in other words one which is not so difficult to make as to be beyond the reasonable cost of such a contrivance.

With these and other objects in view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter described, andpointed out in the appended claim and illustrated inthe accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within Vthe scope of the appended claim, Without departing from the specification @frein-.rs Patent. i Patented Aug, Application lled March 12, 1920.

spirit or `sacrificing any of the advantages ofthe invention. t

A few of the many possible embodiments of the invention are illustrated in the accompanying drawings, in which-:-

y Figure 1 is a front elevation of a sash- 4holder constructed in `accordance with the present invention, showing the same in opverativekposition on, a window Fig. 2 isa .section taken on line 2 2 of'F ig. 1; Fig. 3 1s a front elevation of one of the elements of the sash-holder, its cover being removed to show` the interior construction; Fig. 4: is aside elevation of the other element of the sash-holder; Fig. 5 is an elevation similar to the one shown in Fig. 1, with the elementsof the sash-holder in reverse positions; Fig. 6 is a front elevation of amodified' construction; andfFig. 7'is a section taken on line 7-7 of Fig. 6.`

Referring now to Figs. 1 to 4, inclusive, jof the drawings, the numeral 10 indicatesY a window jamb provided with vertically extendingparallel strips 11, between which slides the. sash 12. Ilhe sash-holder comprises two elements, oneof which is carried by the jamb andthe other one by the sash.

yThe element carried bythe jamb comprises preferably a metallic casing 13, disposed in a mortise 14 in the jamb. The vface plate 15 of said casing extends abovefand below the edges of the casing, whereby the 'latter .maybe secured to the j amb by screwsV .16, .passing intothe jamb.. In this casing is slidably arranged a bearing-head 17, having on opposite sides outwardly' projecting lugs 18, that are seated in registering horizontally extending slots 19 in the sides of the casing 13. In the box 17 is journaled a roller 20. This roller is loosely mounted upon a spindle 21, the ends of which are seated in the slots mentioned. A. spring 22 is disposed in the casing 18 in rear of the bearing-box 17, it having a tendency to project the roller 2 0 through an opening 23 'in the face plate of the casing, as far as the slots 19 permit. The roller is provided with a peripheral groove 24, extending in a. plane at right angles to the axis of the spindle 21. In the said groove are formed equidistantly spaced depressions 25, for a purpose hereinafter to be described.

The other element of the sash-holder is mountedppon the sash, and more particularly upon a stile 26 thereof. This element comprises a vertically extending metallic strip 27, secured by screws 28, or otherwise, to the stile, and having formed thereon a longitudinal rib 29, fitting' the groove 211 in the roller 20. From the rib project outwardly equidistantly spaced lugs 30, adapted to be seated in the depressions 25.

In use, a pair of sash holding devices is associated with each sash, that is tov say on each stile of the sash is mounted a strip 27, and with each strip coperates a rollercarrying casing 13 on the respective jamb. The springs 22 project the rollers 20 a suitable distance beyond the casings 13 into engagement with the strips 27. The strips 27 andthe rollers coperating therewith constiti'ite, in fach/toothed racks and pinions, the pinions rotating as the sash is being Vmoved up or down. The interlocking pinions and racks permit the sash to be moved up or down by `force, but hold the sash at any desired position against its weight.

Inasmueh as the ribs 29 on the strips 27 it snugly the grooves 24 in the rollers, the sash will be effectively prevented from rattling.y

The modification illustrated in Fig. 5 differs from the one above described in that the positions of the roller-carrying casing 13 and the strip 27 are reversed, the casing 13 being in this instance mounted upon the sash and the strip 27 on the jamb. The function and operation of the elements are otherwise the same as of those described in connection with Figs. 1 to 11, inclusive, of the drawings.

The modification illustrated in Figs. 6

and 7 dilier's slightly from the one shown in Fig. 5, more particularly in that means are provided for adjusting the position'o the roller 2O in the casingv 13.` This means comprises two washers 31, one on each end of the spindle .21 of thek roller, the said spindle being in this instance somewhat larger, its ends projecting beyond the slotted sides of the casing 13. Each washer is provided with an inwardly extending projection 32, seatedr in the respective slot 19 between the spindle 21 and the adjacent end of the said slot. Nuts 33, in engagement with the ends of the spindle, hold the washers 31 in position upon the casing 13.

When the sash-holder is mounted upon a window, it is assembled with the elements in the positions shown in Figs. 6 and 7 of the drawings, operating in the manner above described. If, in time, the sash and jambs of the window shrink, the washers 31, with their projections, are removed from the sashholder, permitting the roller to move outward, under the action of its spring, as far as the slots 19 will permit, thereby compensating Jfor the shrinkage.

In the case illustrated in Figs. 6 and 7 oit' the drawings, the metallic strip 27 is provided with outwardly projecting ridges 34- in parallel relation to the rib 29, and more particularly one on each side of the rib. The roller 2O moves between these ridges, which serve thus as an additional means for preventing rattling of the window.

What I claim is A sash-holder comprising a casing having registering horizontal slots in its sides, a bearing-head slidably arranged in said casing having lugs seated in said slots, a spindle in said bearing-head carrying a roller adapted to project through an opening in said casing, the ends of said spindle being seated in said slots, a springfin said casing abutting against said bearing-head, and washers upon the ends of said spindle having projections extending into said slots, said projections being disposed between said spindle ends and the adjacent slot ends.
